Maintenance system for maintaining an energy accumulator arrangement

摘要

An energy accumulator arrangement for an electromedical implant includes a battery, a capacitor, and a charging device which is designed to supply an electric charge from the battery to the capacitor according to a charging program. A maintenance system for maintaining the energy accumulator arrangement includes a monitoring device contained in the implant which captures a physical parameter value of the energy accumulator arrangement; an evaluation unit for evaluating the captured physical parameter value and generating a resulting evaluation result signal; a transceiver contained in the implant which sends the captured physical parameter value to the evaluation unit, and receive the evaluation result signal generated by the evaluation unit; and additionally a control unit contained in the implant which controls the charging device and the monitoring device, and adapts the charging program as a function of the evaluation result signal.

a. a monitoring device contained in the implant, the monitoring device being configured to capture a physical parameter value of the energy accumulator arrangement; b. an evaluation unit configured to:
(1) evaluate the captured physical parameter value, and(2) generate an evaluation result signal as a function of the captured physical parameter value; c. a transceiver contained in the implant, the transceiver being configured to:
(1) send the captured physical parameter value to the evaluation unit, and(2) receive the evaluation result signal generated by the evaluation unit; and d. a control unit contained in the implant, the control unit being configured to:
(1) control the charging device and the monitoring device to periodically charge the capacitor by:
(a) initiating the charging of the capacitor by the charging device;(b) interrupting the charging process for a first defined time period after a first defined capacitor voltage of the capacitor has been reached;(c) continuing the charging of the capacitor after expiration of the first time period;(d) capturing the physical parameter value in the form of a second time period which at least approximates the time period between:
i. the start of continued charging, andii. the time when the first defined capacitor voltage is reached again;(e) sending the value of the captured second time period to the evaluation unit using the transceiver;(f) receiving the evaluation result generated by the evaluation unit as a function of the captured second time period, and(2) adapt the charging program as a function of the evaluation result signal.
